HENRY R. WAHL, OF ELVINS, MISSOURI.

APPARATUS FOR DISPOSAL OF WASTE ROCK FROM CONCENTRATING-MILLS.

Specification of Letters Patent.

Patented Feb. 14, 1911.

Application filed February 28, 1910. Serial No. 546,326.

To all whom it may concern:

Be it known that I, HENRY R. \VAHL, a citizen of the United States, residing at the town of Elvins, in the county of St. Francois and State of Missouri, have invented certain new and useful Improvements in Apparatus for Disposal of Vaste Rock from Concentrating-Mills, of which the fol1owing is a specification, reference being had therein to the accompanying drawings.

This invention relates to conveying and distributing apparatus, and more part cularly to apparatus to be used in dlsposmg of waste rock, or other material, from mines, concentrating mills for lead ore, or other places.

This invention consists in the provision of a movable hopper-car which supports a terminal of a track, upon which track ears are operated to deliver the material to said hopper-car and, also, to deposit the material behind said movable car, in order to make a roadbed for the track.

Another object of this invention is the provision of means for receiving the material and of means for distributing sa-me either directly ahead of the apparatus or alongside thereof, in order to'make a fill upon which a portable track is temporarily laid for the apparatus.

This invention, further, consists in certain novel features of construction and combination of parts, which will be hereinafter more fully described and pointed out in the claims.

In the drawings forming part of this specification, like numbers of reference denote like parts wherever they occur, and Figure 1 is a plan view of the complete apparatus; Fig. 2 is a side elevation of same; Fig. 3 is asectional view on the line 33, Fig. 1; Fi 4 is a sectional view on the line 4-4, Fig. 1; Fig. 5 is a sectional View on the line 55, Fig. 4:; Fig. 6 is a sec tional view on the line 66, Fig. 3; Fig. 7 is a plan view of means for regulating the tension of one of the conveyers; Fig. 8 is a perspective view. of a valve for one of the discharge pipes; Fig. 9 is a bottom plan view of one of the discharge pipes; Fig. 10 is a sectional View on the line 10-10, Fig. 9; Fig. 11 is a sectional View on the line 11-11, Fig. 10; and Fig. 12 is a plan view of an alternate form of the apparatus. 4

The framework 1 of a car 2, which is movable upon a comparatively short track 3, supports a bin 4 and, also, the terminal of a track 5, which is located above said bin and which extends to the concentrating mill, mine, or other place where the material to be disposed of is located. Cars 6, preferably of the bottom-discharge type, are operated upon track 5 by means of an electric or steam locomotive (not shown in the drawings) or by any othersuitable means. Car 2 is preferably made long enough to allow two or more cars 6 at a time to occupy a position above bin 4 in order to discharge their contents into same, but, when it is desirable, said car 2 can be made of such length that only one car 6 can occupy a DOSllllOll above said bin.

The track 5 is laid upon a fill 7, which terminates at the rear end of track 3. A portion of track 5 spans the open space between the end of fill 7 and the rear end of car 2 and is supported b means of a )air of girders 8. Each girc er 8 is hinge in any suitable manner to the end of car 2, in order to allow the end of same that rests on the fill to move up or down relative to car 2 when said ear is moved forwardly in the manner hereinafter described.

A plurality of discharge pipes 9 project from bin 4. Each of said pipes is provided with a valve 10 which is pivoted at 11 to said pipe and which bears a spout 12, and, when said valve is moved to a position to cause spout 12 to communicate with pipe 9, the material in said ipe passes out through said spout 12. Said valve is connected to an eccentric 13 by means of an arm 14 pivoted at 15 to said valve. Said eccentric 13- bears a clutch member 16, and is loosely mounted on a shaft 17, journaled in journalboxes 18. A clutch 19 is splined to shaft 17 and is adapted to slide thereon, a lever 20 being arranged to move said clutch into and out of engagement with clutch member 16, in order to cause eccentric 13 to move valve 10 to a position to open or close pipe 9.

Each shaft 17 is provided with a pulley 21. A belt 22 drives pulley 21 and is driven by a pulley 23 on the next shaft 17. A belt 24'dr1ves one of the pulleys 21, and receives its power from a pulley 25 on a-shaft 26 journaled in journal-boxes 27, which are supported by means of brackets 28 or the.

like. A belt 29 receives its power from a motor 30 or other suitable source and drives a pulley 31 on said shaft 26.

A. belt oonvever 32, preferably of the 25 1 eighty degrees, the free end. of said boom being supported by means of a guy 43 which upon a boom 41.

Robins type, is arranged to receive thematerial discharged from spouts 12. Said conveyer runs ona pair of pulleys 33, and travels in the dipection indicated by the arrows in Fig. 3, in order to cause the material carried thereby .to be discharged into a hopper 34 supported by standards 35 or the like at the forward end of ear 2. One of the pulleys 33 is mounted on shaft 26, and drives the conveyer 32. The other one of said pulleys 33 is mounted on a shaft 36, which is journaled in journal-boxes 37, each of said journal-boxes being arranged to be adjusted by means of a hand-wheel 38 on a screwthreaded rod 39 or other suitable device attached thereto for the purpose of regulating the tension of the belt conveyer 32.

A belt conveyer 40, also of the Robins type, is arranged to receive the material dis charged from hopper 34, and is mounted Said boom is supported on a roller-bearing turn-table 42 on the front end of car, 2, and isfree'toswing in a plane more or less horizontal to the horizon through substantially one hundred and is fastened to an upright of the framework I. Said conveyer 40 runs on'a pair .of pulleys 44 and travels in the direction indicated by the arrows in Fig. 4 to cause the material carried thereby .to be discharged at the forward end of boom 41, in order to make the fill 45 upon which the track 3 is laid.

One'of the pulleys 44 is mounted on a shaft 46, which is journaled in journal-boxes 47,-

each of said j ournal-boxes 47 being arranged to be adjusted by means of a hand-wheel 48 on a screw-threaded rod 49, or other suitable device, for the purpose of regulating the tension of belt conveyer 40. The other one of said pulleys 44 is mounted on a shaft 50 journaled in journal-boxes 51, and drives said conveyer 40. A belt 52 drives pulley 53 on said shaft 50, and receives its power from a motor 54. or other suitable driving means, preferably located in a cage 55 borne by boom 41. r l

When an electric locomotive is used for the purpose ofoperating cars 6 upon track 5, a trolley wire 56 is strung in the usual manner-over said track. A trolley pole 57 borne by framework 1 of car 2 isarranged to engage trolley wire 56 in order to supply motive power to the motors 30 and 54 for the operation of conveyers 32'and 40.

In the alternate form depicted in Fig. 12, the-car 2 is made sufficiently wide to extend over two parallel tracks 3 and is supported thereby. The bin 4, track 5, conveyers 32 and 40, andboom 41 are in duplicate and are arranged in the mann'er-hereinabove described. A central power station is preferably located on said car 2, and consists of a boiler 58 and engine 59, which operates a dynamo 60, ffomwhich electrical motive power is obtained and conducted to the motors for operating the various moving parts.

The apparatus is best adapted to operate over sloping ground or over a valley, the commencement of operation being at as high a location as possible. As long as the difference in elevation between the grade of fill 7 and the grade of the natural ground upon which said fill is made is substantially equal to the difference in elevation between the grade of track 5 and the grade of track 3,. said track 3 is laid upon the natural ground. After these preliminaries, the apparatus is used as follows: Each car 6 is brought to a position over girders 8 to cause the contents thereof to be dumpedbetween said girders and to be deposited upon the end of fill 7. The material is deposited in this manner upon the end of fill 7 8 until same reaches the rear end of track 3. The rail joint at the end of each girder 8 that rests upon the fill 7 is broken and the car 2 is moved forwardly in any suitable manner upon track 3 until same clears the 'lastrail joints of said track Two rails are laid in the spacethat is made in track 5, when the car 2 is moved forwardly upon track 3, and are connected in the usual manner to the adjoining rails of said track 5. The rear section of track 3 is removed and is laid as the forward section of said track. The material is then deposited upon the end of fill Z .7 until same reaches the rear end of track 3, and the car -2 is again moved forwardly as hereinabovedescribed. Thecar 2 is thus moved forwardly until the forward" end of boom 41 reaches over the point where the natural ground upon which fill 7 is made slopes downwardly from the grade of track 3. The material is then dumped into 'bin 4, and the conveyers 32 and 40 are set into operation, and the valves 10 are moved in the manner hereinabove described to cause thematerial to pass through spouts 12 11 to said conveyer 32. Said conveyer 32 de posits the material carried thereby into hope per. 34, which delivers same to the conveyer 40. Said conveyer 40 delivers the material from the forward end of boom 41, whichis 1 swung in any suitable manner into position to carry the material to the point desired, and there to dump it. When the material thus deposited reaches the grade of track 3,

the car 2 is moved a few feet ahead, and the 12 operation is repeated. After each forward movement of car 2 upon track 3, the boom 41 deposits the material to the extent of its distributing area in order to build the fill or roadbed 45 for track 3. When on 2 is 2 moved forwardy far enough to clear the last rail joints of said track 3, the rear section of said track is moved to the front end, and the fill 7- is lengthened in the manner hereinabove described.

. upon saidtrack and adapted to'deposit the Once --started, this apparatus makes its own roadbed without the necessity of using trestles 0 false-Work, and is capable of filling up a 10st an entire valley by.returni ng to the original starting point and oflsetting the car 2 andtrack v3 the Width ofthe The operation of the alternate form of the apparatus is substantially the same as the operation of the form just described, With the exception that the moving parts are driven w th motive power generated by a centralpower station located onsaid oar. Due to the duplication 'of parts in this form, the apparatus can distribute double the amount of material and over a great-er area than is possible with the form of apparatus first described.

I claim: 1.. Inan apparatus of'the character described, the combination of a movable car,

a main track having a terminal supported thereby, a roadbed for said track, a-bm borne by said car' and arranged beneath the terminal of'said track, loading cars operated niat'er'ialinto said bin and, also, upon the end of said roadbed behind sald movable car, a conveyer arranged to receive the material discharged from said bin, a swinging .-ear,- and a conveyer borne by said boom and arranged to receive the material discharged from said first mentloned eonveyen 2.
